FLASH-LIGHT.

Specification of Letters Patent.

Patent-ea sept. se, isis.,

Application led January 29, 1915. Serial No. 5.039.

To'aZZiriom it may concern Be it known that I, HARRY M. Konizrzii, a subject of the Czar of Russia, and a resident of the city of New York, borough of .the Bronx, in the county of the Bronx and device serving not as a housing for the usual apparatus embodied in the instruments above referred to, but an electric cell, lamp and circuit contacts are arranged in the casing, sothat by the pushing ot' a button the lamp can be lighted.

A further object of the invention is to provide a novel arrangement of lamp, pushbutton contacts and cell within the narrow l compass of an ordinary watch case, and at the-same time provide a cell ot considerable capacity compared with the available space for its storage.

A furtherl object of the invention is the provision of a push-button switch which takes the form ot' the stem ot the watch or instrument the device simulates, and b v the pushing of the stem the circuit ot 'the lamp is completed, and if it is desired to maintain lthe circuit completed for a considerable length of time the usual ring of the watch or other instrument can be so engaged with the knob of the stem as to keep the latter pressed in in closed circuit position. v

Still another object of the invention is the provision of an electric lamp within the casing 'and normally concealed when the cover of the casing is closed, and which is adapted to be automatically lighted when the stem of the deviceis pressed in to unloclcthe' `coveifwhich latter springs open Just like the cover of a Watch, such a device atfording amusement, in that when the person carrying the Watch is asked thetime-he may take out the device and pretend to open itas an 'ordinary Watch-is opened, and instead ota timepiece being revealed, a light will flash. Besides being usedasv aynovelty the device can perform thelusual serviceV of a Hash light;

lilith such objects in view,land others which will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts which will be set tort-h with particularity in the following description and claims appended hereto.

ln the accompanying drawing, which illustrates certain embodiments of the invention and wherein similar characters of reference indicate corresponding parts in all the lviews, Figure l is a plan view of the flash light novelty in the torni of a closed watch, the cover of the watch being open to section on the line 2 2, Fig. l; Fig. 3 is a view ot a modilied form, wherein the cover automatically springs open when the stem of the device is pressed; Fig. l is a section on the line 4.-l, Fig. 3; Fig. 5 is an edge view ot the watch, showing the manner in which the same is held to operate the pushbutton; and Fig. G is a perspective view of the dry cell.

Referring to the drawing, A designates a casing which in size and shape resembles an ordinariv watch, and this casing is provided with a suitable cover l, preferably, although not necessarily, fastened to the casing A by a hinge '2. Attached to the casing is a barrel 3 in which is a slidable stemid, and on the stem is a knob 5. and on the barrel is a pivoted ring 6. These parts 3, l, 5- and G are of the same appearance as the stem construction ot' a watch, so that in its external aspect the article simulates a. watch,`or any other instrument ot the pocket type.

The casing A and cover l constitutes the body ot an electric flash light, and. the circular wall T ot the casing has a threaded socket 8 for receiving a small electric lamp i) which screws into the socket, the base of the lamp having a central Contact lO which is adapted to engage a spring contact ll, and also having` a threaded shell contact l2 which grounded on the casing A, which is et metal, and the lilament l3nt' the lamp has its terminals connected with thecontacts l0 and l2. The bulb of the lamp is preferablyT tlush with thel circulan wall of the casing so as not to be liable to injury. IThe current is furnished'by a dry,cell B made up of units suitably bound together in the usual manner. vThe lamp lis diametrically opposite from thestem'd, and `the-cell is disposed intermediate the stem andl the show the internal arrangementg'Fig. 2 is a lamp, and the greatest length of the cell is transverse to the diametrical line in which thefstem and lamp are located. By this arrangement a cell of maximum capacity is provided for the available space within the casing A. To prevent shiftingl of the cell, stops or abutments 14 and 15 are arranged in the casing, as clearly shown in Fig. 1. The terminal 1G of the cell has soldered or otherwise Asecured thereto the spring con' tact 11, which latter is an l.shaped strip of metal projecting laterally from the terminal 16, and thence along the side of the cell. The other terminal 17 of the cell is provided by cutting an opening 18 in the paper cover 19 of the cell and applying a drop of solder to the metal surface exposed by making the opening 18 This drop of solder or terminal 17 is directly in line with the inner end of the stem e, so'that by pushing the stem inwardly the circuit of the cell and lamp is completed. The,barrel 3 is hollow and contains a spring 2O which presses on the knob 5 to which the stein l is fastened, and consequently, by pressing the knob inwardly the circuit is completed. A convenient method of holding the flash light and operating the push button switch is shown in Fig. 5, where the ring 6 is grasped between the thumb and first finger while the thumb is pressing on the knob or pushbutton 5.

If it is desired to maintain a permanent light the push-button can be held pressed by engaging a cross-bar 9.1 on the ring 6 with a notch 22 in the knob 5, as clearly shown in Fig. 2.

ln the construction shown in Figs. 3 and 4l, the lamp 9 is normally concealed within the casing A of the device, and this lamp is screwed into a socket S which is fastened to and electricallyconnected with the casing A. rIhe cell B 1s arranged in the casing reversely to the arrangement of Fig. 1, and the spring contact 11 is in engagement with the stein #1, and the terminal 17 has a laterally extending L-shaped contact strip 17"L which extends under the socket S and engages the entral contact of the lamp` 9', as clearly shown in Fig. 4:. The cover 1 is adapted to be held closed by a catch Q3 on the stem il', and by pressing the stem in wardly the catch is released, so that the cover l will ily open, due to a spring 24 incorporated in the hinge 2 between they electrode and contains theg-active material,

and centrally disposed within. this cylinder 25 is the other-electrode 26. The electrode 26 of one unit is connected bya wire 27 with. the cylinder of the adjacent unit, `the two units being separated by a strip of insulation 2S, andthe covering 19 serving to hold the units together. The other electrode 9.6 forms the terminal 16 to which the spring contact 11 is connected.

From the foregoing description taken in connection with the accompanyihngdrawing, the advantages .of the construction and method of operation will be readily understood by those skilled in the art to l'which the invention appertains, and while I have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be madewhen desired as are within the scope of the vappended claims.

Having thus described my invention, I claim as new and desire to. secure by Letters Patent: l
